About this product
A-Powder CoCrMo is a gas-atomized cobalt-chromium-molybdenum superalloy for laser powder bed fusion (LPBF): outstanding wear and corrosion resistance, high hardness and biocompatibility — the standard for dental frameworks, orthopedic implants and wear-critical parts. US-produced, lot-certified for production.
Why engineers choose A-Powder CoCrMo
Four things a materials team verifies before qualifying a powder.
Outstanding wear resistance
High hardness and wear resistance retained at elevated temperature — bearings, joints and wear-critical parts.
Biocompatible
The medical and dental standard — crowns, bridges, frameworks and orthopedic implants (ASTM F75, ISO 13485 workflows).
Corrosion-resistant, lot-certified
Resists body fluids, oxidation and hot corrosion — full COA per lot with PSD, chemistry, density and flow.
US-produced, fast dispatch
Made in the USA and shipped from Los Angeles in 5–10 business days. Need a tighter cut or an official purchase request? Just ask.
How we supply it
Every lot ships as a verified process, not a bag of powder — melted, atomized, tested, certified.
Step 01
Melted & atomized
US VIGA (vacuum induction melt + gas atomization) for spherical, low-oxygen cobalt-chrome powder.
Step 02
Tested & certified
Every lot checked for PSD, chemistry, apparent density and flow — full COA with a traceable lot number.
Step 03
Dispatched from LA
Bottled or hoppered and shipped from Los Angeles in 5–10 business days.

Chemical composition
| Element | Content | Element | Content |
|---|---|---|---|
| Cobalt (Co) | Balance | Iron (Fe) | ≤ 0.75% |
| Chromium (Cr) | 26.0–30.0% | Nickel (Ni) | ≤ 0.50% |

| Si / Mn | ≤ 1.0% | Nitrogen (N) | ≤ 0.25% |
Heat treatment & processing
- Stress relief before plate removal is recommended to control residual stress.
- Application-specific solution / aging or HIP improves ductility and closes porosity for implantable parts.
- High hardness makes CoCrMo difficult to machine — near-net AM geometry is a key advantage.
Typical applications

Unedited feedback from customers who reorder A-Powder Cobalt Chrome Powder (CoCrMo) for Metal 3D Printing | LPBF Compatible – 10 kg / 22 lbs.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

★★★★★
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

★★★★★
COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
